Welcome to our resource for MG Car Information.
MG MGA - CAN YOU IDENTIFY THIS ENGINE ??
|I just acquired an MGA 1500 parts car and with it came an extra engine. The engine has a prefix of |
15NH XXXXX. I can find no reference to this # in the Moss catalogue Production Data section for MGA. Can anyone tell me what it is ?? Thanks !!
|Sounds like a column change, high compression motor from an A55 Austin Cambridge.|
|There seems to be a letter missing. The N would be for column gearchange and the H for high compression.|
A common engine in North America would be the Nash Metropolitan, but I would expect the engine number to be 15FNH......
|M F Anderson|
|I felt that there must be a letter missing too but a second check of the engine plate confirms the full number is: 15NH 98894 and silly me ..... the valve cover has an Austin plate on it. It of course was covered by a tarp that I raised it only high enough to see the engine plate originaly. So I think Austin Cambridge is the best guess ??|
Are you sure its not 15MH? i.e. M, not N. If so Morris Oxford Series 3 or 4.
I triple checked and no mistaking it .... it is defintiely an "N" ..... and again it has an Austin plate on the valve cover.
| The BMC engine chart suggests that this motor is from a 1957/8 A55 Austin Cambridge.|
See chart BMC 'B' SERIES ENGINES USE.( 1953 to 1981.)
|Thanks Dave, I can see from the chart the reference to #15 by itself for the A55 Austin Cambridge and assume that my "N" would refer to column shift and my "H" would refer to high compression. How did you determine the specific year range as 1957/58 ?? I don't see any model year reference other than the section category 1953 to 1981. Is the answer as obvious as those are the only two years of production for the A55 or am I missing something ?? Please excuse my ignorance if the answer is that simple. My experience/knowledge is primarily with MGA's and even that is often limited. Thanks !!|
|Mike, you are unable to tell the year from the chart but the MK1 Cambridge was only produced from 1957/58. The MK2 Cambridge produced from 1959/61 had an engine prefix 15AMW, and yes you're correct the N is column change and the H is high compression.|
|Dave, Steve and Mick ..... many thanks for all your input. Once again the BBS proves to be a valuable resource !!|
|I fired off a question about this to Neil Cairns, an authority on MG and B-Series engines. He responded to me that the NH suffix was a new one for him.|
Michael, perhaps you could respond to Neil with the details and perhaps a photo so that he can add it to his research.
